Abstract: Guards for covering rotating discs of power hand tools wherein said guard includes a movable guard for covering a normally exposed portion of a disc and which is pivotably mounted relative to a body of the power tool such that the it is movable from a first covering position in a plane substantially parallel to a rotational plane of the disc to a second withdrawn position in which the movable guard extends generally transversely to the rotational plane of the disc thereby allowing maximum disc coverage yet permitting disc use in restricted spaces.

Abstract: Temperature responsive valves for regulating fluid flow in a supply line such as to a showerhead or faucet wherein the valves include a slide valve assembly which is movably positioned within a bore extending in transverse communication with respect to a primary fluid passageway extending through the body of the valve between a fluid inlet and an outlet. Each valve further includes a pressure chamber in which the slide valve assembly is mounted which communicates with the fluid inlet. Temperature responsive force generators are used to control flow into the pressure chamber such that when the fluid temperature is above a predetermined temperature, the pressure within the pressure chamber increases, thereby forcing the slide valve assembly from an open to a closed position to thereby substantially terminate flow through the primary fluid passageway.

Abstract: A radial arm saw is provided with pairs of outside and inside lower blade guards which normally extend outwardly beyond the cutting blade of the saw. The lower blade guards are normally locked in covering relationship relative to the saw blade unless released by the operation of a safety lock assembly including a pair of pivotable stop members which are engageable with the lower blade guards. The safety lock assembly includes a handle for pivoting and releasing the stop members when the radial arm saw is used in a crosscutting mode and a separate release rod which extends from the forward end of the saw assembly to the rear end thereof and which is operable to release the stop members when the saw is utilized in a rip cut mode.

Abstract: Multi-functional showerheads which include a central water supply shaft along which an outer housing is selectively adjustable so that the showerheads are operable in a first mode wherein the housing rotates to provide a massage action and in a second mode to provide a fixed or rotary shower spray.

Abstract: A vehicle's input switches relating to ignition, lights and moisture or rain provide responsive inputs that feed through a digital logic circuit to outputs of an electronic switching device for automatically activating the vehicle's lights and wipers.An alarm may be activated if certain input switches are turned on when the ignition is off.The digital logic circuit may be discrete, a programmable read only memory (PROM) or a programmable logic array (PLA).The electronic switching device may constitute a driver circuit and an integrated circuit which includes both a relay switching circuit and a switched circuit, for example a metal-oxide-semiconductor (MOS) driver and a power metal-oxide-semiconductor field-effect-transistor (MOSFET) integrated circuit.

Abstract: A control system for automatically turning on the headlights (and parking lights) of a vehicle has an input section that includes the ignition switch, the manually operated windshield wiper switch, and condition responsive light sensor and moisture sensor switches. These switches operate through a logic circuitry through an output section to turn on and to keep turned on the lights when any of certain switch combinations are turned on:a) ignition, windshield wiper, light sensor and moisture sensor;b) ignition, windshield wiper and light sensor;c) ignition, windshield wiper and moisture sensor;d) ignition and windshield wiper;e) ignition, light sensor and moisture sensor;f) ignition and light sensor; org) ignition and moisture sensor.In the event that the windshield wiper is turned off the light level sensor causes the lights to be turned off.

Abstract: Extendable trays for use in conventional rural route mailboxes for facilitating the placement and removal of mail with respect thereto wherein the trays are constructed utilizing scored or integrally hinged sheet material which is selectively folded into a generally flat or planar configuration or package for shipping or distribution and which is assembled by a postal customer so as to be of a size and configuration to be cooperatively and slidingly received within a particular mailbox. In one form of the invention, the sheet material may be selectively folded into a number of sizes so that trays of varying dimensions may be formed from the same sheet of material.

Abstract: Material handling systems for supporting and transferring articles within defined areas from one location to another in which cooperatively spaced support plates are mounted within the defined areas and carriages or shuttles are movably supported by the plates in a manner such that the carriages may be guided along a network of optional routes along open passageways created between the plates. The carriages may be mechanized or manually maneuverable and may include load lifting and adjusting components which are selectively operated to raise, support, re-orient and lower the articles so that such articles may be transferred and repositioned as desired.

Abstract: A closet organizer for supporting a plurality of articles of clothing such as pants and skirts from a clothes rod in a closet wherein the organizer includes a housing which is selectively suspended from the clothes rod and is stabilized with respect thereto and from which a telescoping clothing rack assembly is slideably carried. The clothing rack assembly includes at least one telescoping slide member which is received within the housing and from which a plurality of vertically spaced pairs of horizontally swingable clothing support arms are suspended. The clothing support arms may be selectively moved forwardly of the clothes rod and thereafter adjustably pivoted outwardly relative to one another so as to facilitate placement and retrieval of articles of clothing with respect thereto.
